Q3. Predictiоn (10 pоints) Use testDаtа in this quesitоn а) Using the testData and models model1 (2a), model2(2b), model3 (2d), predict 'medical_cost' for each row in testData. Calculate the "Mean squared prediction error" for each model's predictions. (3 points) i) Which model performed the best according to the value of mean squared prediction error? (2 points) ii) Interpret the mean squared prediction value of model1 in the context of prediction accuracy. (2 points) b) Based on the MSPE values in Q3a, which model appears to balance bias and variance most effectively? Explain. (3 points)
